The answer is "Yes", you can make the suspension too stiff.
Where is that limit? I honestly don't know. It depends on a lotta other factors like road conditions (need softer springs on bumpier roads), tires, air pressure in tires, spring height, etc.
For MY driving conditions, the suspension I have now is NOT too stiff for the street. However, I wouldn't want it significantly stiffer either. I also wouldn't want it quite as stiff as it is now if I had to drive on roads with lotsa potholes (i.e. Northern US).
Going TOO stiff will result in things like the car becoming "twitchy" in corners, pronounced (and sudden) oversteer, and far outrunning the ability of the tires to hold the road.
